Letters Patent No. 109,488, dated-November 22g 1870.

IMPROVEMENT IN- CREAM'iSTRAlNERS.

The Schedule referred to in these Letters Patent anc'i'makng part of thesame.

provcnient, by which my invention may be distin' guished' from others ofa similar class, together with such parts as l' claim and desire tosecure by Letters Patent.

My invention relates to implements made use of for the purpose ofstraining 'and ruining crea-m preparatory to churning; and

The nature thereof consists of a slightly-conical shaft operated by acrank, and provided uponits outer surface and bottom with grooves, whichare both spiral and tapering, in combination with a cylindricalstrainer, the periphery ot lwhichis perforated.

In the accompanying drawing which illustrates my invention 'and formsapart of the specification thereof, in which like part-s' 'are designatedhy corresponding letters- Y Figure l is 'a sideelevation of theimplement.

Figure 2 illustrates the shaft, provided with spiral grooves and crank.

The construction, operatiomand relative arrangement of'thc componentparts'of my invention are as follows A represents the vessel into whichthe crcamis poured, and the bottom of which is made convex,

sloping downward toward-thc center, ywhere the perforated cup orstrainer B is attached to it.

The-cylindrical shaft U is placed inthe vesselin a vertical position,the lower end of the shaft being made large enough to lit the 4strainerB at the bottom, where it rests, andA tapering slightly upward as far asthe top of the strainer, from which point to the upper extremity thcshaft is made' much smaller.

The upper endis held in position by the barD'ex- I tending across thetop of the vessel over the center, the shaft passing through an aperturein it, and each end of the bar being fastened to the brim of the vessel.

The lower portion of the shaft C contained by the cup or strainer B isprovided withseveral.grooves E, which commence at a point a in the shaftand run downward in a spiral course, graduallydiminishing in -size andterminating iu a. horizont-al direction near the bottom.

Across the bottom of theshaft, and running from the center outward,several curvilinear grooves F are also ont, which are intended to workthe cream toward the perforated cylinder, the bottom of the cup orstrainer being closed. 4

The upper end of the shaftC is provided wit-h a crank, by whichit isoperated. The machine is operated by placing it over achurn or anyvessel desired. The cream is then pouredi and the crank turned in theproper'direction. By the opera-tion of the shaft C and the grooves E andF the cream is forced rapidly through the strainer, with a uniformpressure against it in every direction. y K

Having described the construction and operation of my invention, I would.state that I am aware of the i patent granted to G. J2 Bennett on the9th of July,

1867, and do not claim the devices'tliereiu described.

I claim and desire to secure by Letters Patentelhe slightly-conical"lshaft C, provided with the vtapering and spiral grooves E and F, incombination with the perforated cylinder or strainer, as and for thepurposes described. Y

In testimony that I claim the foregoing, I- have hereunto set my handand seal this 11th day of June, 1870.
